- Progressive disclosure principles to minimize token usage
- Anti-patterns documentation to guide LLM behavior
- HTTP API integration for all search functionality
- Common workflows with composition examples

Structure:
- SKILL.md: Entry point with temporal trigger patterns
- principles/: Progressive disclosure + anti-patterns
- operations/: 12 search operation files

Plan: Migrate to Skill-Based Search (Deprecate MCP)
Goal
Replace MCP search tools with a skill-based approach, reducing session
start context from ~2,500 tokens to ~250 tokens. Clean migration, no
toggles.
Implementation Steps
1. Add HTTP API Endpoints to Worker Service
File: src/services/worker-service.ts
Add 10 new routes that wrap existing SessionSearch methods:
- GET /api/search/observations?query=...&format=index&limit=20&project=...
- GET /api/search/sessions?query=...&format=index&limit=20
- GET /api/search/prompts?query=...&format=index&limit=20
- GET /api/search/by-concept?concept=discovery&format=index&limit=5
- GET /api/search/by-file?filePath=...&format=index&limit=10
- GET /api/search/by-type?type=bugfix&format=index&limit=10
- GET /api/context/recent?project=...&limit=3
- GET /api/context/timeline?anchor=123&depth_before=10&depth_after=10
- GET
/api/timeline/by-query?query=...&mode=auto&depth_before=10&depth_after=10
- GET /api/search/help - Returns available endpoints and usage docs
All endpoints return JSON. Skill parses and formats for readability.
2. Create Search Skill
File: plugin/skills/search/SKILL.md
Frontmatter:
---
name: search
description: Search claude-mem persistent memory for past sessions,
observations, bugs fixed, features implemented, decisions made, code
changes, and previous work. Use when answering questions about history,
finding past decisions, or researching previous implementations.
---
Content: Instructions for all 9 search types using curl to call HTTP
endpoints, formatting guidelines, common workflows.
3. Remove MCP Search Server
Files to modify:
- Remove plugin/.mcp.json entry for claude-mem-search
- Keep src/servers/search-server.ts for reference but don't build it
- Update scripts/build-plugin.js to skip building search-server.mjs
- Archive search-server implementation (don't delete, for reference)
4. Update Documentation
File: CLAUDE.md
Remove MCP search references, add skill search explanation:
- Token savings: ~2,250 tokens per session
- How skill auto-invokes (model-driven, not user-driven)
- Available search operations
- Examples of triggering searches
5. Add Migration Notice
File: CHANGELOG.md or release notes
Document the breaking change:
## v5.4.0 - Skill-Based Search Migration
**BREAKING CHANGE**: MCP search tools have been replaced with a
skill-based approach.
**What changed**:
- Removed 9 MCP search tools (search_observations, search_sessions, etc.)
- Added `search` skill that provides the same functionality
- Reduced session start context by ~2,250 tokens
**Migration**: None required. Claude automatically uses the search skill
when needed.
The skill provides the same search capabilities with better token
efficiency.
**Why**: Skill-based search uses progressive disclosure (~250 tokens for
frontmatter)
instead of loading all 9 tool definitions (~2,500 tokens) on every session
start.
6. Testing Checklist
- All 10 HTTP endpoints return correct data
- Skill auto-invokes when asking about past work
- Skill successfully calls endpoints via curl
- Skill formats results as readable markdown
- Worker restart updates endpoints
- Skill distributed correctly with plugin
- No MCP search server registered
- Session start context reduced by ~2,250 tokens
Token Impact
- Before: ~2,500 tokens (9 MCP tool definitions)
- After: ~250 tokens (skill frontmatter only)
- Savings: ~2,250 tokens per session start
User Experience
New behavior:
- User: "What bug did we fix last session?"
- Claude sees skill description matches → invokes search skill
- Skill loads full instructions → uses curl to call HTTP API → formats
results
- User sees formatted answer
No user action required: Migration is transparent, searches work
automatically.
Build & Deploy
npm run build # Builds skill, skips MCP server
npm run sync-marketplace # Syncs plugin with skill
npm run worker:restart # Restart worker with new HTTP endpoints
Rollout
1. Ship as breaking change in v5.4.0
2. Update plugin marketplace listing
3. All users get automatic token savings on update
4. Archive MCP search implementation for reference

# Claude-Mem Documentation Folder
## What This Folder Is
This `docs/` folder is a **Mintlify documentation site** - the official user-facing documentation for claude-mem. It's a structured documentation platform with a specific file format and organization.
## File Structure Requirements
### Mintlify Documentation Files (.mdx)
All official documentation files must be:
- Written in `.mdx` format (Markdown with JSX support)
- Listed in `docs.json` navigation structure
- Follow Mintlify's schema and conventions
The documentation is organized into these sections:
- **Get Started**: Introduction, installation, usage guides
- **Best Practices**: Context engineering, progressive disclosure
- **Configuration & Development**: Settings, dev workflow, troubleshooting
- **Architecture**: System design, components, technical details
### Configuration File
`docs.json` defines:
- Site metadata (name, description, theme)
- Navigation structure
- Branding (logos, colors)
- Footer links and social media
## What Does NOT Belong Here
**Planning documents, design docs, and reference materials should go in `/context/` instead:**
Files that should be in `/context/` (not `/docs/`):
- Planning documents (`*-plan.md`, `*-outline.md`)
- Implementation analysis (`*-audit.md`, `*-code-reference.md`)
- Error tracking (`typescript-errors.md`)
- Design documents not part of official docs
- PR review responses
- Reference materials (like `agent-sdk-ref.md`)
**Example**: The deleted `VIEWER.md` was moved because it was implementation documentation, not user-facing docs.
## Current Files That Should Be Moved
These `.md` files currently in `docs/` should probably be moved to `context/`:
- `typescript-errors.md` - Error tracking
- `worker-service-architecture.md` - Implementation details (not user-facing architecture)
- `processing-indicator-audit.md` - Implementation audit
- `processing-indicator-code-reference.md` - Code reference
- `worker-service-rewrite-outline.md` - Planning document
- `worker-service-overhead.md` - Analysis document
- `CHROMA.md` - Implementation reference (if not user-facing)
- `chroma-search-completion-plan.md` - Planning document
## How to Add Official Documentation
1. Create a new `.mdx` file in the appropriate subdirectory
2. Add the file path to `docs.json` navigation
3. Use Mintlify's frontmatter and components
4. Follow the existing documentation style
## Development Workflow
**For contributors working on claude-mem:**
- Read `/CLAUDE.md` in the project root for development instructions
- Place planning/design docs in `/context/`
- Only add user-facing documentation to `/docs/`
- Test documentation locally with Mintlify CLI if available
## Summary
**Simple Rule**:
- `/docs/` = Official user documentation (Mintlify .mdx files)
- `/context/` = Development context, plans, references, internal docs
docs/CHROMA.md → docs/context/CHROMA.md

# Claude-Mem Context Documentation
## What This Folder Is
This `docs/context/` folder contains **internal documentation** - planning documents, design references, audits, and work-in-progress materials that support development but are NOT user-facing.
## Folder Structure
```
docs/
├── public/ ← User-facing Mintlify docs (DO NOT put internal docs there)
│ └── *.mdx - Official documentation
└── context/ ← You are here (Internal documentation)
├── *.md - Planning docs, audits, references
├── *-plan.md - Implementation plans
├── *-audit.md - Code audits and reviews
├── agent-sdk-*.md - SDK reference materials
└── subdirs/ - Organized by topic
```
## What Belongs Here
**Internal Documentation** (`.md` format):
- Planning documents (`*-plan.md`, `*-outline.md`)
- Implementation analysis (`*-audit.md`, `*-code-reference.md`)
- Error tracking (`typescript-errors.md`)
- Design documents not ready for public docs
- PR review responses
- Reference materials (like `agent-sdk-ref.md`)
- Work-in-progress documentation
- Technical investigations and postmortems
- Architecture analysis documents
**Examples from this folder:**
- `mem-search-technical-architecture.md` - Deep technical reference
- `search-architecture-analysis.md` - Implementation analysis
- `agent-sdk-ref.md` - SDK reference for developers
- `typescript-errors.md` - Error tracking during development
- `worker-service-architecture.md` - Internal architecture notes
- `processing-indicator-audit.md` - Code audit document
## What Does NOT Belong Here
**User-Facing Documentation** goes in `/docs/public/`:
- User guides and tutorials
- Official architecture documentation
- Installation instructions
- Configuration guides
- Best practices for users
- Troubleshooting guides
**Rule of Thumb:**
- If a user would read it → `/docs/public/` (as `.mdx`)
- If only developers/contributors need it → `/docs/context/` (as `.md`)
## File Organization
### By Type
- `*-plan.md` - Implementation plans for features
- `*-audit.md` - Code audits and reviews
- `*-postmortem.md` - Analysis of issues or incidents
- `*-reference.md` - Technical reference materials
- `*-analysis.md` - Architecture or design analysis
### By Topic
- Create subdirectories for related documents
- Example: `claude-code/` for Claude Code specific docs
- Example: `architecture/` for internal architecture notes
## Development Workflow
### When to Create Context Docs
1. **Planning Phase** - Before implementing a feature
- Create `feature-name-plan.md`
- Outline implementation steps
- Document decisions and tradeoffs
2. **During Development** - Track issues and decisions
- Create `feature-name-audit.md` for code reviews
- Update `typescript-errors.md` for build issues
- Document gotchas in topic-specific files
3. **After Implementation** - Preserve knowledge
- Create `feature-name-postmortem.md` if issues occurred
- Update architecture analysis documents
- Archive plan docs (don't delete - useful for history)
### Graduating to Public Docs
When internal docs are polished enough for users:
1. Convert `.md` to `.mdx` format
2. Add Mintlify frontmatter
3. Move to appropriate `/docs/public/` subdirectory
4. Add to `docs.json` navigation
5. Keep original in `/docs/context/` for reference
## Summary
**Simple Rule**:
- `/docs/context/` = Internal docs, plans, references, audits ← YOU ARE HERE
- `/docs/public/` = Official user documentation (Mintlify .mdx files)
**Purpose**: This folder preserves development context, design decisions, and technical knowledge that helps contributors understand WHY things work the way they do, even if users don't need those details.

## HTTP Endpoints Architecture
### Location
`src/services/worker-service.ts` (lines 108-118, 748-1174)
### Endpoints (10 total)
| Endpoint | Method | Purpose | Used By |
| -------------------------- | ------ | ----------------------------------- | ---------------- |
| `/api/search/observations` | GET | Full-text search observations | mem-search skill |
| `/api/search/sessions` | GET | Full-text search session summaries | mem-search skill |
| `/api/search/prompts` | GET | Full-text search user prompts | mem-search skill |
| `/api/search/by-concept` | GET | Find observations by concept tag | mem-search skill |
| `/api/search/by-file` | GET | Find work related to specific files | mem-search skill |
| `/api/search/by-type` | GET | Find observations by type | mem-search skill |
| `/api/context/recent` | GET | Get recent session context | mem-search skill |
| `/api/context/timeline` | GET | Get timeline around point in time | mem-search skill |
| `/api/timeline/by-query` | GET | Search + timeline in one call | mem-search skill |
| `/api/search/help` | GET | API documentation | mem-search skill |
### Implementation Pattern
**Example: Search Observations**
```typescript
// src/services/worker-service.ts:748-781
private handleSearchObservations(req: Request, res: Response): void {
try {
// 1. Parse query parameters
const query = req.query.query as string;
const format = (req.query.format as string) || 'full';
const limit = parseInt(req.query.limit as string, 10) || 20;
const project = req.query.project as string | undefined;
// 2. Validate required parameters
if (!query) {
res.status(400).json({ error: 'Missing required parameter: query' });
return;
}
// 3. Call SessionSearch (shared data layer)
const sessionSearch = this.dbManager.getSessionSearch();
const results = sessionSearch.searchObservations(query, { limit, project });
// 4. Format response based on format parameter
res.json({
query,
count: results.length,
format,
results: format === 'index' ? results.map(r => ({
id: r.id,
type: r.type,
title: r.title,
subtitle: r.subtitle,
created_at_epoch: r.created_at_epoch,
project: r.project,
score: r.score
})) : results
});
} catch (error) {
logger.failure('WORKER', 'Search observations failed', {}, error as Error);
res.status(500).json({ error: (error as Error).message });
}
}
```
### Characteristics
**Pros:**
- ✅ Simple HTTP GET requests (curl-friendly)
- ✅ Standard REST API pattern
- ✅ Easy to test and debug
- ✅ No MCP protocol overhead
- ✅ Works with any HTTP client
**Cons:**
- ⚠️ Parameter parsing duplicated across 10 endpoints
- ⚠️ Format conversion logic duplicated
- ⚠️ Error handling pattern repeated
---
## MCP Search Server Architecture
### Location
`src/servers/search-server.ts` (1,781 lines)
### Status
- **Built:** ✅ Yes (`plugin/scripts/search-server.mjs`, 74KB)
- **Configured:** ✅ Yes (`.mcp.json` line 3-6)
- **Used:** ❌ No (deprecated in v5.4.0)
- **Maintained:** ⚠️ Source kept for reference
### Tools (9 total)
| Tool Name | Purpose | Line |
| ----------------------- | -------------------------------------- | -------- |
| `search_observations` | Search observations with FTS5 + Chroma | 348-422 |
| `search_sessions` | Search session summaries | 438-490 |
| `search_user_prompts` | Search user prompts | 506-558 |
| `find_by_concept` | Find by concept tag | 574-626 |
| `find_by_file` | Find by file path | 642-694 |
| `find_by_type` | Find by observation type | 710-762 |
| `get_recent_context` | Get recent sessions | 778-830 |
| `get_context_timeline` | Get timeline context | 846-950 |
| `get_timeline_by_query` | Search + timeline | 966-1064 |
### Implementation Pattern
**Example: Search Observations (MCP)**
```typescript
// src/servers/search-server.ts:348-422
{
name: 'search_observations',
description: 'Search observations using full-text search across titles, narratives, facts, and concepts...',
inputSchema: z.object({
query: z.string().describe('Search query for FTS5 full-text search'),
format: z.enum(['index', 'full']).default('index').describe('...'),
...filterSchema.shape
}),
handler: async (args: any) => {
try {
const { query, format = 'index', ...options } = args;
let results: ObservationSearchResult[] = [];
// Hybrid search: Try Chroma semantic search first, fall back to FTS5
if (chromaClient) {
try {
// Step 1: Chroma semantic search (top 100)
const chromaResults = await queryChroma(query, 100);
if (chromaResults.ids.length > 0) {
// Step 2: Filter by recency (90 days)
const ninetyDaysAgo = Date.now() - (90 * 24 * 60 * 60 * 1000);
const recentIds = chromaResults.ids.filter((_id, idx) => {
const meta = chromaResults.metadatas[idx];
return meta && meta.created_at_epoch > ninetyDaysAgo;
});
// Step 3: Hydrate from SQLite
if (recentIds.length > 0) {
const limit = options.limit || 20;
results = store.getObservationsByIds(recentIds, { orderBy: 'date_desc', limit });
}
}
} catch (chromaError: any) {
console.error('[search-server] Chroma query failed, falling back to FTS5:', chromaError.message);
}
}
// Fall back to FTS5 if Chroma unavailable or returned no results
if (results.length === 0) {
results = search.searchObservations(query, options);
}
// Format results
if (format === 'index') {
return {
content: [{
type: 'text',
text: results.map((r, i) => formatObservationIndex(r, i)).join('\n\n') + formatSearchTips()
}]
};
} else {
return {
content: results.map(r => ({
type: 'resource',
resource: {
uri: `claude-mem://observation/${r.id}`,
mimeType: 'text/markdown',
text: formatObservationResult(r)
}
}))
};
}
} catch (error: any) {
return { content: [{ type: 'text', text: `Error: ${error.message}` }] };
}
}
}
```
### Characteristics
**Pros:**
- ✅ MCP protocol support
- ✅ Hybrid search (Chroma + FTS5)
- ✅ Rich formatting (markdown, resources)
- ✅ Comprehensive error handling
**Cons:**
- ❌ Not used by skill (deprecated)
- ❌ ~2,500 token overhead for tool definitions
- ❌ More complex than HTTP
- ❌ Still being built despite deprecation
---
## DRY Violation Analysis
### Areas of Duplication
#### 1. **Parameter Parsing** (10 HTTP endpoints + 9 MCP tools)
**HTTP Endpoints:**
```typescript
// Repeated in each endpoint handler
const query = req.query.query as string;
const format = (req.query.format as string) || "full";
const limit = parseInt(req.query.limit as string, 10) || 20;
const project = req.query.project as string | undefined;
if (!query) {
res.status(400).json({ error: "Missing required parameter: query" });
return;
}
```
**MCP Tools:**
```typescript
// Repeated in each tool handler
const { query, format = "index", ...options } = args;
if (!query) {
throw new Error("Missing required parameter: query");
}
```
**Violation:** Parameter parsing logic duplicated 19 times (10 + 9)
#### 2. **Format Conversion** (Index vs Full)
**HTTP Endpoints:**
```typescript
results: format === "index"
? results.map((r) => ({
id: r.id,
type: r.type,
title: r.title,
subtitle: r.subtitle,
created_at_epoch: r.created_at_epoch,
project: r.project,
score: r.score,
}))
: results;
```
**MCP Tools:**
```typescript
if (format === "index") {
return {
content: [
{
type: "text",
text: results.map((r, i) => formatObservationIndex(r, i)).join("\n\n"),
},
],
};
} else {
return {
content: results.map((r) => ({
type: "resource",
resource: {
uri: `claude-mem://observation/${r.id}`,
mimeType: "text/markdown",
text: formatObservationResult(r),
},
})),
};
}
```
**Violation:** Format conversion logic duplicated with different output formats
#### 3. **Search Logic Duplication**
**HTTP Endpoints:**
```typescript
const sessionSearch = this.dbManager.getSessionSearch();
const results = sessionSearch.searchObservations(query, { limit, project });
```
**MCP Tools:**
```typescript
// Hybrid search with Chroma fallback
if (chromaClient) {
const chromaResults = await queryChroma(query, 100);
// ... complex hybrid logic ...
}
if (results.length === 0) {
results = search.searchObservations(query, options);
}
```
**Violation:** MCP has hybrid Chroma+FTS5 search, HTTP only has FTS5
#### 4. **Error Handling**
**HTTP Endpoints:**
```typescript
try {
// ... handler logic ...
} catch (error) {
logger.failure("WORKER", "Search observations failed", {}, error as Error);
res.status(500).json({ error: (error as Error).message });
}
```
**MCP Tools:**
```typescript
try {
// ... handler logic ...
} catch (error: any) {
return { content: [{ type: "text", text: `Error: ${error.message}` }] };
}
```
**Violation:** Different error handling patterns
### DRY Compliance at Data Layer ✅
**Good news:** Both architectures use the **same data layer**:
```
HTTP Endpoints → SessionSearch → SQLite
MCP Tools → SessionSearch → SQLite
```
The `SessionSearch` class is the **single source of truth** for data access. No duplication there.
---
## Is curl the Best Approach?
### Current Approach: curl Commands
**Example from skill:**
```bash
curl -s "http://localhost:37777/api/search/observations?query=authentication&format=index&limit=5"
```
### Alternative Approaches
#### 1. **MCP Tools** (Deprecated)
**Pros:**
- Native Claude Code protocol
- Rich type definitions
- Better error handling
- Resource formatting
**Cons:**
- ❌ ~2,500 token overhead per session
- ❌ More complex to implement
- ❌ Requires MCP server process
- ❌ Less accessible for external tools
**Verdict:** MCP was deprecated for good reasons (token overhead). curl is better.
#### 2. **Direct Database Access** (Not feasible)
**Pros:**
- No HTTP overhead
- No worker process needed
**Cons:**
- ❌ Skills can't access files directly
- ❌ No way to execute TypeScript/SQLite from skill
- ❌ Would require building native bindings
**Verdict:** Not possible with current skill architecture.
#### 3. **HTTP API via curl** (Current) ✅
**Pros:**
- ✅ Simple, standard protocol
- ✅ Works with skill architecture
- ✅ Easy to test (curl in terminal)
- ✅ Language-agnostic
- ✅ No MCP token overhead
- ✅ RESTful design
**Cons:**
- ⚠️ Requires worker service running
- ⚠️ HTTP parsing overhead (minimal)
**Verdict:** **Best approach given constraints.**
### Why curl is Optimal
1. **Skill Constraints:** Skills can only execute shell commands. curl is the standard HTTP client.
2. **Token Efficiency:** No tool definitions loaded into context (~2,250 token savings).
3. **Progressive Disclosure:** Skill loads gradually, HTTP requests are made only when needed.
4. **Debuggability:** Easy to test endpoints manually with curl.
5. **Cross-platform:** curl available on all platforms.
---
### Question: "Is it routing into the search-service MCP file or is it a DRY violation?"
**Answer:** Both architectures exist, creating a DRY violation:
1. **HTTP Endpoints** (worker-service.ts) ← **Used by skill**
2. **MCP Server** (search-server.ts) ← **Deprecated but still built**
### Current State
```
mem-search skill → HTTP API (worker-service.ts) → SessionSearch → SQLite
↑
MCP search server (deprecated) → SessionSearch ──────────────────────┘
```
Both use the same data layer (SessionSearch), but:
- ❌ Parameter parsing duplicated
- ❌ Format conversion duplicated
- ❌ MCP has hybrid Chroma search, HTTP doesn't
- ❌ MCP still being built despite deprecation
**You said:** "We are intentionally exposing API search endpoints

- Already supports format=index/full for token efficiency
- Well-documented in skill operation guides
- Clean JSON responses
---
## Architectural Recommendations
### Immediate Actions
#### 1. **Remove MCP Search Server** (Reduce Maintenance Burden)
**Problem:**
- MCP server is deprecated but still being built
- Adds 1,781 lines of maintenance burden
- Creates confusion about which search to use
- DRY violation with HTTP endpoints
**Recommendation:**
```bash
# Remove from build pipeline
# scripts/build-hooks.js - already commented out, make permanent
# Delete configuration
rm plugin/.mcp.json
# Archive source (don't delete, keep for reference)
git mv src/servers/search-server.ts archive/search-server.ts.archived
# Remove built file
rm plugin/scripts/search-server.mjs
```
**Impact:**
- ✅ Reduces build time
- ✅ Eliminates confusion
- ✅ Reduces maintenance burden
- ✅ Removes DRY violation
- ⚠️ Loses hybrid Chroma search in MCP (but HTTP doesn't have it anyway)
#### 2. **Add Hybrid Search to HTTP Endpoints** (Feature Parity)
**Problem:** MCP server has Chroma hybrid search, HTTP endpoints don't
**Recommendation:**
```typescript
// src/services/worker-service.ts
private async handleSearchObservations(req: Request, res: Response): Promise<void> {
try {
const { query, format, limit, project } = this.parseSearchParams(req);
// Try hybrid search first if Chroma available
let results = await this.hybridSearch(query, { limit, project });
// Fallback to FTS5 if Chroma unavailable
if (results.length === 0) {
const sessionSearch = this.dbManager.getSessionSearch();
results = sessionSearch.searchObservations(query, { limit, project });
}
res.json(this.formatSearchResponse(query, results, format));
} catch (error) {
this.handleSearchError(res, 'Search observations failed', error);
}
}
// Extract shared methods
private parseSearchParams(req: Request): SearchParams { /* ... */ }
private async hybridSearch(query: string, options: SearchOptions): Promise<any[]> { /* ... */ }
private formatSearchResponse(query: string, results: any[], format: string): any { /* ... */ }
private handleSearchError(res: Response, message: string, error: any): void { /* ... */ }
```
**Impact:**
- ✅ Adds Chroma semantic search to HTTP API
- ✅ Makes HTTP API feature-complete
#### 3. **Extract Shared Search Logic** (DRY Refactoring)
**Problem:** 10 HTTP endpoints have duplicated parameter parsing and formatting
**Recommendation:**
```typescript
// src/services/search/SearchController.ts (new file)
export class SearchController {
constructor(private sessionSearch: SessionSearch, private chromaSync: ChromaSync) {}
async searchObservations(params: SearchParams): Promise<SearchResponse> {
// Shared logic for observations search
const results = await this.hybridSearch(params);
return this.formatResponse(results, params.format);
}
async searchSessions(params: SearchParams): Promise<SearchResponse> {
// Shared logic for sessions search
}
// ... other search methods
private async hybridSearch(params: SearchParams): Promise<any[]> {
// Shared hybrid search logic
}
private formatResponse(results: any[], format: "index" | "full"): SearchResponse {
// Shared formatting logic
}
private parseParams(req: Request): SearchParams {
// Shared parameter parsing
}
}
```
**Usage in worker-service.ts:**
```typescript
private searchController: SearchController;
private handleSearchObservations(req: Request, res: Response): void {
try {
const params = this.searchController.parseParams(req);
const response = await this.searchController.searchObservations(params);
res.json(response);
} catch (error) {
this.handleSearchError(res, error);
}
}
```
**Impact:**
- ✅ Eliminates 90% of duplication across 10 endpoints
- ✅ Single source of truth for search logic
- ✅ Easier to test (test controller, not HTTP layer)
- ✅ Easier to maintain
- ✅ Easier to add new search endpoints

## Summary
### Current Architecture Issues
1. ❌ **Dual search implementations** (HTTP + deprecated MCP)
2. ❌ **DRY violations** across 19 search handlers
3. ❌ **MCP server still built** despite deprecation
4. ❌ **HTTP missing hybrid Chroma search** (MCP has it)
5. ❌ **No shared controller layer** for search logic
### Is curl the Best Approach?
**Yes.** ✅
Given the constraints:
- Skills can only execute shell commands
- Token efficiency vs MCP (~2,250 token savings)
- Standard REST pattern, easy to consume
curl + HTTP API is the optimal architecture.
### Is it Routing into search-service or DRY Violation?
**DRY violation.** ❌
Both architectures exist and duplicate logic:
- HTTP endpoints (worker-service.ts) ← ACTIVE
- MCP server (search-server.ts) ← DEPRECATED but BUILT
They share the data layer (SessionSearch) but duplicate:
- Parameter parsing
- Format conversion
- Error handling
- Search orchestration (MCP has Chroma, HTTP doesn't)
### Recommendations Priority
**High Priority:**
1. ✅ Remove MCP search server entirely (archive source)
2. ✅ Add hybrid Chroma search to HTTP endpoints
3. ✅ Extract SearchController for shared logic
**Medium Priority:**
5. Add API versioning (/api/v1/search/\*)
6. Add rate limiting for external access
**Low Priority:** 7. OpenAPI/Swagger documentation
9. WebSocket support for real-time search
### Action Plan
**Phase 1: Cleanup (1 day)**
- Remove .mcp.json
- Archive search-server.ts
- Update CLAUDE.md to reflect removal
- Update build scripts to skip MCP server
**Phase 2: Feature Parity (2 days)**
- Port hybrid Chroma search from MCP to HTTP
- Test all 10 endpoints with hybrid search
- Update skill documentation
**Phase 3: DRY Refactoring (3 days)**
- Create SearchController class
- Extract shared logic (parsing, formatting, errors)
- Refactor 10 HTTP handlers to use controller
- Add comprehensive tests
- Document API for external consumption
- Add authentication/authorization (if needed)
- Add rate limiting
- Create OpenAPI spec

# Skill Audit Report
**Date:** 2025-11-10
**Validation:** Anthropic's official skill-creator documentation
**Skills Audited:** mem-search, search
## Executive Summary
The mem-search skill achieves 100% compliance across all dimensions. The search skill meets technical requirements but fails effectiveness metrics critical for auto-invocation.
**mem-search:** Production-ready. No changes required.
**search:** Requires three critical fixes before Claude reliably discovers and invokes this skill.
## mem-search Skill Results
**Status:** ✅ PASS
**Compliance:** 100% technical, 100% effectiveness
**Files:** 17 (202-line SKILL.md + 13 operations + 2 principles)
### Strengths
The skill demonstrates exemplary effectiveness engineering:
1. **Trigger Design (85% concrete)**
- Five unique identifiers: claude-mem, PM2-managed database, cross-session memory, session summaries, observations
- Nine scope differentiation keywords
- Explicit boundary: "NOT in the current conversation context"
- Minimal overlap with Claude's native capabilities
2. **Capability Visibility (100%)**
- All nine operations include inline "Use when" examples
- Decision guide reduces complexity from nine operations to five common cases
- No navigation friction
3. **Structure**
- 202 lines (60% under limit)
- Perfect progressive disclosure with token cost documentation
- Clean file organization: operations/ and principles/ directories
- No content duplication
### Issues
**One false positive:** Line 152 contains backslashes in regex notation `(bugfix\|feature\|decision)`. This documents parameter syntax, not Windows paths. No action required.
## search Skill Results
**Status:** ⚠️ NEEDS IMPROVEMENT
**Compliance:** 100% technical, 67% effectiveness
**Files:** 13 (96-line SKILL.md + 12 operations)
### Critical Effectiveness Issues
Three failures prevent reliable auto-invocation:
#### Issue 1: Insufficient Scope Differentiation
**Problem:** Description contains only two differentiation keywords (threshold: ≥3). Claude cannot distinguish this skill from native conversation memory.
**Current description:**
```text
Search claude-mem persistent memory for past sessions, observations, bugs
fixed, features implemented, decisions made, code changes, and previous work.
Use when answering questions about history, finding past decisions, or
researching previous implementations.
```
**Domain overlap analysis:**
- Claude answers natively: "What bugs did we fix?" (current conversation)
- Claude needs skill: "What bugs did we fix last week?" (external database)
**Fix required:**
```text
Search claude-mem's external database of past sessions, observations, and
work from previous conversations. Accesses persistent memory stored outside
current session context - NOT information from today's conversation. Use when
users ask about: (1) previous sessions ("what did we do last week?"),
(2) historical work ("bugs we fixed months ago"), (3) cross-session patterns
("how have we approached this before?"), (4) work already stored in claude-mem
("what's in the database about X?"). Searches FTS5 full-text index across
typed observations (bugfix/feature/refactor/decision/discovery). For current
session memory, use native conversation context instead.
```
This adds eight differentiation keywords: "external database", "past sessions", "previous conversations", "outside current session", "NOT information from today's", "last week", "months ago", "already stored in claude-mem".
#### Issue 2: Weak Trigger Specificity
**Problem:** Only 44% concrete triggers (threshold: >50%). Only one unique identifier (threshold: ≥2).
**Abstract triggers (low specificity):**
- "history" (could mean git history, browser history)
- "past work" (could mean files, commits, documents)
- "decisions" (could mean any decision tracking)
- "previous work" (could mean current session earlier)
- "implementations" (could mean code in current conversation)
**Concrete triggers (high specificity):**
- "claude-mem" (unique system name)
- "persistent memory" (system-specific)
- "sessions" (cross-session concept)
- "observations" (system-specific)
**Concrete ratio:** 4/9 = 44% (fails 50% threshold)
**Fix required:** Add system-specific terminology: "HTTP API", "port 37777", "FTS5 full-text index", "typed observations". See combined description in Issue 1 fix.
#### Issue 3: Wasted Content in Body
**Problem:** Lines 10-22 contain "When to Use This Skill" section in SKILL.md body. This loads AFTER triggering, wastes ~200 tokens, provides no value.
**Reference:** [Anthropic's skill-creator documentation](https://github.com/anthropics/anthropic-quickstarts/tree/main/skill-creator) states: "The body is only loaded after triggering, so 'When to Use This Skill' sections in the body are not helpful to Claude."
**Fix required:** Delete lines 10-22 entirely. Move triggering examples to description field (already included in Issue 1 fix).
### Strengths
The skill demonstrates strong structure:
- Excellent progressive disclosure (96-line navigation hub)
- Strong decision guide (reduces 10 operations to common cases)
- 100% capability visibility (all operations show purpose inline)
- No forbidden files or content duplication
- Clean operations/ directory structure
### Warning
**Minor:** Description uses imperative "Use when" instead of third person. Change to "Useful for" or "Invoked when" for consistency with skill-creator best practices.
## Comparison
| Metric | mem-search | search | Impact |
|--------|-----------|---------|--------|
| Concrete triggers | 85% | 44% | search harder to discover |
| Unique identifiers | 5+ | 1 | search less distinct |
| Scope differentiation | 9 keywords | 2 keywords | **search conflicts with native memory** |
| Body optimization | Clean | Wasted section | search wastes tokens |
| Overall effectiveness | 100% | 67% | search needs fixes |
## Critical Recommendations
The search skill requires three changes before production use:
1. **Rewrite description** to add scope differentiation and concrete triggers (see Issue 1 fix)
2. **Delete lines 10-22** from SKILL.md body
3. **Convert to third person** - change "Use when" to "Useful for"
**Why this matters:** Without scope differentiation, Claude assumes "What bugs did we fix?" refers to current conversation, not the external claude-mem database. This causes systematic under-invocation.
## Reference Implementation
The mem-search skill serves as a reference implementation for:
- Trigger design with explicit scope boundaries
- Progressive disclosure with token efficiency documentation
- Inline capability visibility eliminating navigation friction
- Decision guides reducing cognitive load
Study mem-search when creating skills that overlap with Claude's native capabilities.

# Claude-Mem Public Documentation
## What This Folder Is
This `docs/public/` folder contains the **Mintlify documentation site** - the official user-facing documentation for claude-mem. It's a structured documentation platform with a specific file format and organization.
## Folder Structure
```
docs/
├── public/ ← You are here (Mintlify MDX files)
│ ├── *.mdx - User-facing documentation pages
│ ├── docs.json - Mintlify configuration and navigation
│ ├── architecture/ - Technical architecture docs
│ ├── usage/ - User guides and workflows
│ └── *.webp, *.gif - Assets (logos, screenshots)
└── context/ ← Internal documentation (DO NOT put here)
└── *.md - Planning docs, audits, references
```
## File Requirements
### Mintlify Documentation Files (.mdx)
All official documentation files must be:
- Written in `.mdx` format (Markdown with JSX support)
- Listed in `docs.json` navigation structure
- Follow Mintlify's schema and conventions
The documentation is organized into these sections:
- **Get Started**: Introduction, installation, usage guides
- **Best Practices**: Context engineering, progressive disclosure
- **Configuration & Development**: Settings, dev workflow, troubleshooting
- **Architecture**: System design, components, technical details
### Configuration File
`docs.json` defines:
- Site metadata (name, description, theme)
- Navigation structure
- Branding (logos, colors)
- Footer links and social media
## What Does NOT Belong Here
**Planning documents, design docs, and reference materials go in `/docs/context/` instead:**
Files that belong in `/docs/context/` (NOT here):
- Planning documents (`*-plan.md`, `*-outline.md`)
- Implementation analysis (`*-audit.md`, `*-code-reference.md`)
- Error tracking (`typescript-errors.md`)
- Internal design documents
- PR review responses
- Reference materials (like `agent-sdk-ref.md`)
- Work-in-progress documentation
## How to Add Official Documentation
1. Create a new `.mdx` file in the appropriate subdirectory
2. Add the file path to `docs.json` navigation
3. Use Mintlify's frontmatter and components
4. Follow the existing documentation style
5. Test locally: `npx mintlify dev`
## Development Workflow
**For contributors working on claude-mem:**
- Read `/CLAUDE.md` in the project root for development instructions
- Place planning/design docs in `/docs/context/`
- Only add user-facing documentation to `/docs/public/`
- Test documentation locally with Mintlify CLI before committing
## Testing Documentation
```bash
# Validate docs structure
npx mintlify validate
# Check for broken links
npx mintlify broken-links
# Run local dev server
npx mintlify dev
```
## Summary
**Simple Rule**:
- `/docs/public/` = Official user documentation (Mintlify .mdx files) ← YOU ARE HERE
- `/docs/context/` = Internal docs, plans, references, audits

name: mem-search
description: Search claude-mem's persistent cross-session memory database to find work from previous conversations days, weeks, or months ago. Access past session summaries, bug fixes, feature implementations, and decisions that are NOT in the current conversation context. Use when user asks "did we already solve this?", "how did we do X last time?", "what happened in last week's session?", or needs information from previous sessions stored in the PM2-managed database. Searches observations, session summaries, and user prompts across entire project history.
---
# Memory Search
Access claude-mem's persistent cross-session memory through HTTP API. Find past work, understand context across sessions, and learn from previous decisions.
## When to Use This Skill
**Use when users ask about work from PREVIOUS sessions** (not current conversation):
### Temporal Triggers (Key Indicators)
- "Did we **already** fix this bug?" or "Have we seen this error **before**?"
- "How did we solve X **last time**?" or "What approach did we take **previously**?"
- "What did we do in **yesterday's/last week's/last month's** session?"
- "**When** did we last work on this?" or "What's the **history** of this file?"
### Cross-Session Queries
- "Show me all authentication-related changes **across all sessions**"
- "What features did we add **last month**?" (not "today" or "this session")
- "Why did we choose this approach **before**?" (decisions from past sessions)
- "What files did we modify **when we added X**?" (historical context)
**Do NOT use** for current session work, future planning, or questions Claude can answer from current conversation context.
## Common Trigger Phrases
This skill activates when detecting phrases about **cross-session history**:
- "Did we already solve this?" / "Have we done this before?"
- "How did we implement X last time?"
- "What did we work on yesterday/last week/last month?"
- "Show me the history of [file/feature/decision]"
- "When did we fix/add/change X?"
- "What was happening around [date/time]?"
- "Catch me up on recent sessions" / "What have we been doing?"
- "What changes to [filename] across all sessions?"
**Unique identifiers:** claude-mem, persistent memory, cross-session database, session history, PM2-managed database
## Available Operations
### Full-Text Search
- **observations** - Search all observations by keyword (bugs, features, decisions, discoveries, changes)
- Use when: "How did we implement X?" or "What bugs did we fix?"
- Example: Search for "authentication JWT" to find auth-related work
- **sessions** - Search session summaries to find what was accomplished when
- Use when: "What did we accomplish last time?" or "What was the goal of that session?"
- Example: Find sessions where "added login feature"
- **prompts** - Find what users have asked about in previous sessions
- Use when: "Did I ask about this before?" or "What did I request last week?"
- Example: Search for "database migration" in past user prompts
### Filtered Search
- **by-type** - Filter observations by type (bugfix, feature, refactor, decision, discovery, change)
- Use when: "Show me all bug fixes" or "List features we added"
- Example: Get all observations with type=bugfix from last month
- **by-concept** - Find observations tagged with specific concepts (problem-solution, how-it-works, gotcha)
- Use when: "What patterns did we discover?" or "Show me gotchas"
- Example: Find all observations tagged with concept "gotcha"
- **by-file** - Find all work related to a specific file path across all sessions
- Use when: "What changes to auth.ts?" or "History of this file"
- Example: Get all work related to "src/auth/login.ts"
### Timeline & Context
- **recent-context** - Get last N sessions with summaries and observations
- Use when: "What's been happening?" or "Catch me up on recent work"
- Example: Get last 3 sessions with limit=3
- **timeline** - Get chronological context around a specific point in time (before/after window)
- Use when: "What was happening around [date]?" or "Show me context from that time"
- Example: Timeline around session 123 with depth 5 before and after
- **timeline-by-query** - Search first, then get timeline context around best match
- Use when: "When did we implement auth?" combined with "show me context around that time"
- Example: Search for "OAuth implementation" then get surrounding timeline
For detailed instructions on any operation, read the corresponding file in [operations/](operations/).
## Quick Decision Guide
**What is the user asking about?**
1. **Recent work** (last 3-5 sessions) → Use **recent-context** with limit=3-5
2. **Specific topic/keyword** (bugs, features, decisions) → Use **observations** search
3. **Specific file history** (changes to a file) → Use **by-file** search
4. **Timeline/chronology** (what happened when) → Use **timeline** or **timeline-by-query**
5. **Type-specific** (all bug fixes, all features) → Use **by-type** filter
**Most common:** Use **observations** search for general "how did we..." questions.
## Progressive Disclosure Workflow (Token Efficiency)
**Core Principle**: Find high-signal items in index format FIRST (~50-100 tokens each), then request full details ONLY for relevant items (~500-1000 tokens each).
**4-Step Workflow:**
1. **Start with Index Format**
- Always use `format=index` initially
- Set `limit=3-5` (not 10-20)
- Review titles and dates to assess relevance
- Token cost: ~50-100 per result
2. **Identify Relevant Items**
- Scan index results
- Discard irrelevant items from list
- Keep only 1-3 most relevant
3. **Request Full Details Selectively**
- Use `format=full` ONLY for specific relevant items
- Token cost: ~500-1000 per result
- **10x cost difference** - be selective
4. **Refine with Filters**
- Use type, dateRange, concepts, files filters
- Paginate with offset if needed
- Narrow scope before expanding limits
**DO:**
- ✅ Start with `format=index` and `limit=3-5`
- ✅ Use filters (type, dateRange, concepts, files) to narrow results
- ✅ Request `format=full` ONLY for specific relevant items
- ✅ Use offset for pagination instead of large limits
**DON'T:**
- ❌ Jump straight to `format=full`
- ❌ Request `limit=20` without assessing index results first
- ❌ Load full details for all results upfront
- ❌ Skip index format to "save a step" (costs 10x more tokens)
See [principles/progressive-disclosure.md](principles/progressive-disclosure.md) for complete workflow with examples and token calculations.
## Quick Reference Table
| Need | Operation | Key Parameters |
|------|-----------|----------------|

- Search composition patterns
## Response Formatting
For guidelines on presenting search results to users, see [operations/formatting.md](operations/formatting.md):
- Index format responses (compact lists with titles/dates)
- Full format responses (complete observation details)
- Timeline responses (chronologically grouped)
- Error handling and user-friendly messages
## Technical Notes
- **Port:** Default 37777 (configurable via `CLAUDE_MEM_WORKER_PORT`)
- **Response format:** Always JSON
- **Search engine:** FTS5 full-text search + structured filters
- **All operations:** HTTP GET with query parameters
- **Worker:** PM2-managed background process
## Error Handling
If HTTP request fails:
1. Inform user the claude-mem search service isn't available
2. Suggest checking if worker is running: `pm2 list` or `pm2 status claude-mem-worker`
3. Offer to help troubleshoot using the troubleshoot skill

# Common Workflows
Step-by-step guides for typical user requests using the search API.
## Workflow 1: Understanding Past Work
**User asks:** "What did we do last session?" or "Catch me up on recent work"
**Steps:**
1. **Get recent context** (fastest path):
```bash
curl -s "http://localhost:37777/api/context/recent?limit=3"
```
2. **Present as narrative:**
```markdown
## Recent Work
### Session #545 - Nov 9, 2024
Implemented JWT authentication system
**Completed:**
- Added token-based auth with refresh tokens
- Created JWT signing and verification logic
**Key Learning:** JWT expiration requires careful handling of refresh race conditions
```
**Why this workflow:**
- Single request gets both sessions and observations
- Optimized for "catch me up" questions
- ~1,500-2,500 tokens for 3 sessions
---
## Workflow 2: Finding Specific Bug Fixes
**User asks:** "What bugs did we fix?" or "Show me recent bug fixes"
**Steps:**
1. **Search by type** (index format first):
```bash
curl -s "http://localhost:37777/api/search/by-type?type=bugfix&format=index&limit=5"
```
2. **Review index results**, identify relevant items
3. **Get full details** for specific bugs:
```bash
curl -s "http://localhost:37777/api/search/by-type?type=bugfix&format=full&limit=1&offset=2"
```
4. **Present findings:**
```markdown
Found 5 bug fixes:
🔴 **#1235** Fixed token expiration edge case
> Handled race condition in refresh flow
> Nov 9, 2024 • api-server
[Click for full details on #1235]
```
**Why this workflow:**
- Progressive disclosure: index first, full details selectively
- Type-specific search is more efficient than generic search
- ~250-500 tokens for index, ~750-1000 per full detail
---
## Workflow 3: Understanding File History
**User asks:** "What changes to auth/login.ts?" or "Show me work on this file"
**Steps:**
1. **Search by file** (index format):
```bash
curl -s "http://localhost:37777/api/search/by-file?filePath=auth/login.ts&format=index&limit=10"
```
2. **Review chronological changes**
3. **Get full details** for specific changes:
```bash
curl -s "http://localhost:37777/api/search/by-file?filePath=auth/login.ts&format=full&limit=1&offset=3"
```
4. **Present as file timeline:**
```markdown
## History of auth/login.ts
🟣 **#1230** Added JWT authentication (Nov 9)
🔴 **#1235** Fixed token expiration bug (Nov 9)
🔄 **#1240** Refactored auth flow (Nov 8)
```
**Why this workflow:**
- File-specific search finds all related work
- Index format shows chronological overview
- Selective full details for deep dives
---
## Workflow 4: Timeline Investigation
**User asks:** "What was happening when we deployed?" or "Show me context around that bug fix"
**Steps:**
1. **Find the event** using search:
```bash
curl -s "http://localhost:37777/api/search/observations?query=deployment&format=index&limit=5"
```
2. **Note observation ID** (e.g., #1234)
3. **Get timeline context**:
```bash
curl -s "http://localhost:37777/api/timeline/context?anchor=1234&depth_before=10&depth_after=10"
```
4. **Present as chronological narrative:**
```markdown
## Timeline: Deployment
### Before (10 records)
**2:45 PM** - 🟣 Prepared deployment scripts
**2:50 PM** - 💬 User asked: "Are we ready to deploy?"
### ⭐ Anchor Point (2:55 PM)
🎯 **Observation #1234**: Deployed to production
### After (10 records)
**3:00 PM** - 🔴 Fixed post-deployment routing issue
```
**Why this workflow:**
- Timeline shows temporal context (what happened before/after)
- Captures causality between events
- All record types (observations, sessions, prompts) interleaved
---
## Workflow 5: Quick Timeline (One Request)
**User asks:** "Timeline of authentication work"
**Steps:**
1. **Use timeline-by-query** (auto mode):
```bash
curl -s "http://localhost:37777/api/timeline/by-query?query=authentication&mode=auto&depth_before=10&depth_after=10"
```
2. **Present timeline directly:**
```markdown
## Timeline: Authentication
**Best Match:** 🟣 Observation #1234 - Implemented JWT authentication
### Context (21 records)
[... timeline around best match ...]
```
**Why this workflow:**
- Single request combines search + timeline
- Fastest path when query is specific
- Auto mode uses top result as anchor
**Alternative:** Use interactive mode for broad queries:
```bash
curl -s "http://localhost:37777/api/timeline/by-query?query=auth&mode=interactive&limit=5"
```
Then choose anchor manually.
---
## Workflow 6: Search Composition
**User asks:** "What features did we add to the authentication system recently?"
**Steps:**
1. **Combine filters** for precision:
```bash
curl -s "http://localhost:37777/api/search/observations?query=authentication&type=feature&dateRange[start]=2024-11-01&format=index&limit=10"
```
2. **Review filtered results**
3. **Get full details** for relevant features:
```bash
curl -s "http://localhost:37777/api/search/observations?query=authentication&type=feature&format=full&limit=1&offset=2"
```
4. **Present findings:**
```markdown
Found 10 authentication features added in November:
🟣 **#1234** Implemented JWT authentication (Nov 9)
🟣 **#1236** Added refresh token rotation (Nov 9)
🟣 **#1238** Implemented OAuth2 flow (Nov 7)
```
**Why this workflow:**
- Multiple filters narrow results before requesting full details
- Type + query + dateRange = precise targeting
- Progressive disclosure: index first, full details selectively
---
## Workflow Selection Guide
| User Request | Workflow | Operation | Token Cost |
|--------------|----------|-----------|------------|
| "What did we do last session?" | #1 | recent-context | 1,500-2,500 |
| "What bugs did we fix?" | #2 | by-type | 500-3,000 |
| "What changes to file.ts?" | #3 | by-file | 500-3,000 |
| "What was happening then?" | #4 | search → timeline | 3,500-6,000 |
| "Timeline of X work" | #5 | timeline-by-query | 3,000-4,000 |
| "Recent features added?" | #6 | observations + filters | 500-3,000 |
## General Principles
1. **Start with index format** - Always use `format=index` first
2. **Use specialized tools** - by-type, by-file, by-concept when applicable
3. **Compose operations** - Combine search + timeline for investigations
4. **Filter early** - Use type, dateRange, project to narrow before expanding
5. **Progressive disclosure** - Load full details only for relevant items
## Token Budget Awareness
**Quick queries** (500-1,500 tokens):
- Recent context (limit=3)
- Index search (limit=5-10)
- Filtered searches
**Medium queries** (1,500-4,000 tokens):
- Recent context (limit=5-10)
- Full details (3-5 items)
- Timeline (depth 10/10)
**Deep queries** (4,000-8,000 tokens):
- Timeline (depth 20/20)
- Full details (10+ items)
- Multiple composed operations
Always start with minimal token investment, expand only when needed.

# Response Formatting Guidelines
How to present search results to users for maximum clarity and usefulness.
## General Principles
1. **Progressive disclosure** - Show index results first, full details on demand
2. **Visual hierarchy** - Use emojis, bold, and structure for scannability
3. **Context-aware** - Tailor presentation to user's question
4. **Actionable** - Include IDs for follow-up queries
5. **Token-efficient** - Balance detail with token budget
---
## Format: Index Results
**When to use:** First response to searches, overviews, multiple results
**Structure:**
```markdown
Found {count} results for "{query}":
{emoji} **#{id}** {title}
> {subtitle}
> {date} • {project}
```
**Example:**
```markdown
Found 5 results for "authentication":
🟣 **#1234** Implemented JWT authentication
> Added token-based auth with refresh tokens
> Nov 9, 2024 • api-server
🔴 **#1235** Fixed token expiration edge case
> Handled race condition in refresh flow
> Nov 9, 2024 • api-server
```
**Type Emojis:**
- 🔴 bugfix

## Error Responses
**No results found:**
```markdown
No results found for "{query}". Try:
- Different search terms
- Broader keywords
- Checking spelling
- Using partial paths (for file searches)
```
**Service unavailable:**
```markdown
The search service isn't available. Check if the worker is running:
```bash
pm2 list
```
If the worker is stopped, restart it:
```bash
npm run worker:restart
```
```
**Invalid parameters:**
```markdown
Invalid search parameters:
- {parameter}: {error_message}
See the [API help](help.md) for valid parameter options.
```
---
## Context-Aware Presentation
Tailor formatting to user's question:
**"What bugs did we fix?"**
→ Use index format, emphasize date/type, group by recency
**"How did we implement X?"**
→ Use full format for best match, include complete narrative and files
**"What was happening when..."**
→ Use timeline format, emphasize chronology and causality
**"Catch me up on recent work"**
→ Use session summary format, focus on high-level accomplishments
---
## Token Budget Guidelines
**Minimal presentation (~100-200 tokens):**
- Index format with 3-5 results
- Compact list structure
- Essential metadata only
**Standard presentation (~500-1,000 tokens):**
- Index format with 10-15 results
- Include subtitles and context
- Clear formatting and emojis
**Detailed presentation (~1,500-3,000 tokens):**
- Full format for 2-3 items
- Complete narratives and facts
- Timeline with 20-30 records
**Comprehensive presentation (~5,000+ tokens):**
- Multiple full results
- Deep timelines (40+ records)
- Session summaries with observations
Always start minimal, expand only when needed.
---
## Markdown Best Practices
1. **Use headers (##, ###)** for hierarchy
2. **Bold important elements** (IDs, titles, dates)
3. **Quote user text** (prompts, questions)
4. **Bullet lists** for facts and files
5. **Code blocks** for commands and examples
6. **Emojis** for type indicators
7. **Horizontal rules (---)** for section breaks
8. **Blockquotes (>)** for subtitles and previews
---
## Examples by Use Case
### Use Case 1: Quick Overview
User: "What did we do last session?"
```markdown
## Recent Work
### 🎯 Session #545 - November 9, 2024
Implemented JWT authentication system
**Key accomplishment:** Added token-based auth with refresh tokens
**Key learning:** JWT expiration requires careful handling of refresh race conditions
```
### Use Case 2: Specific Investigation
User: "How did we implement JWT authentication?"
```markdown
## 🟣 Feature #1234: Implemented JWT authentication
**What happened:**
Implemented a complete JWT authentication system with access and refresh tokens. Access tokens expire after 15 minutes, refresh tokens after 7 days. Added token signing with RS256 algorithm.
**Files:**
- src/auth/jwt.ts (created)
- src/auth/refresh.ts (created)
- src/middleware/auth.ts (modified)
**Key insight:** Refresh race conditions require atomic token exchange logic.
```
### Use Case 3: Timeline Investigation
User: "What was happening around the deployment?"
```markdown
## Timeline: Deployment
[... chronological timeline with before/after context ...]
```
Choose presentation style based on user's question and information needs.

## How to Present Results
Present as reference documentation:
```markdown
## claude-mem Search API Reference (v5.4.0)
Base URL: `http://localhost:37777/api`
### Search Operations
**1. Search Observations**
- **Endpoint:** `GET /search/observations`
- **Description:** Search observations using full-text search
- **Parameters:**
- `query` (required, string): Search terms
- `format` (optional, string): "index" or "full" (default: "full")
- `limit` (optional, number): Max results (default: 20, max: 100)
- **Example:**
```bash
curl -s "http://localhost:37777/api/search/observations?query=authentication&format=index&limit=5"
```
[... continue for all endpoints ...]
```
## Endpoint Categories
The API help response organizes endpoints by category:
1. **Full-Text Search**
- `/search/observations`
- `/search/sessions`
- `/search/prompts`
2. **Filtered Search**
- `/search/by-type`
- `/search/by-concept`
- `/search/by-file`
3. **Context Retrieval**
- `/context/recent`
- `/timeline/context`
- `/timeline/by-query`
4. **Utilities**
- `/help`
## Common Parameters
Many endpoints share these parameters:
- **format**: "index" (summary) or "full" (complete details)
- **limit**: Number of results to return
- **offset**: Number of results to skip (for pagination)
- **project**: Filter by project name
- **dateRange**: Filter by date range
- `dateRange[start]`: Start date (ISO string or epoch)
- `dateRange[end]`: End date (ISO string or epoch)
## Error Handling
**Worker not running:**
Connection refused error. Response: "The search API isn't available. Check if worker is running: `pm2 list`"
**Invalid endpoint:**
```json
{"error": "Not found"}
```
Response: "Invalid API endpoint. Use /api/help to see available endpoints."
## Tips
1. Save help response for reference during investigation
2. Use examples as starting point for your queries
3. Check required parameters before making requests
4. Refer to format options for each endpoint
5. All endpoints use GET method with query parameters
**Token Efficiency:**
- Help response: ~2,000-3,000 tokens (complete API reference)
- Use sparingly - refer to operation-specific docs instead
- Keep help response cached for repeated reference
## When to Use Help
**Use help when:**
- Starting to use the search API
- Need complete parameter reference
- Forgot which endpoints are available
- Want to see all options at once
**Don't use help when:**
- You know which operation you need (use operation-specific docs)
- Just need examples (use common-workflows.md)
- Token budget is limited (help is comprehensive)
## Alternative to Help Endpoint
Instead of calling `/api/help`, you can:
1. **Use SKILL.md** - Quick decision guide with operation links
2. **Use operation docs** - Detailed guides for specific endpoints
3. **Use common-workflows.md** - Step-by-step examples
4. **Use formatting.md** - Response presentation templates
The help endpoint is most useful when you need complete API reference in one response.
## API Versioning
The help response includes version information:
```json
{
"version": "5.4.0",
"skill_migration": true,
"deprecated": {
"mcp_tools": "Replaced by HTTP API in v5.4.0"
}
}
```
Check version to ensure compatibility with documentation.

# Search User Prompts (Full-Text)
Search raw user prompts to find what was actually asked across all sessions.
## When to Use
- User asks: "What did I ask about authentication?"
- User asks: "Find my question about database migrations"
- User asks: "When did I ask about testing?"
- Looking for specific user questions or requests
## Command
```bash
curl -s "http://localhost:37777/api/search/prompts?query=authentication&format=index&limit=5"
```
## Parameters
- **query** (required): Search terms (e.g., "authentication", "how do I", "bug fix")
- **format**: "index" (truncated prompts) or "full" (complete prompt text). Default: "full"
- **limit**: Number of results (default: 20, max: 100)
- **project**: Filter by project name (optional)
- **dateRange**: Filter by date range (optional)
## When to Use Each Format
**Use format=index for:**
- Quick overviews of what was asked
- Finding prompt IDs for full text
- Listing multiple prompts
- **Token cost: ~50-100 per result (truncated to 200 chars)**
**Use format=full for:**
- Complete prompt text
- Understanding the full user request
- **Token cost: Variable (depends on prompt length, typically 100-300 tokens)**
## Example Response (format=index)
```json
{
"query": "authentication",
"count": 5,
"format": "index",
"results": [
{
"id": 1250,
"session_id": "S545",
"prompt_preview": "How do I implement JWT authentication with refresh tokens? I need to handle token expiration...",
"created_at_epoch": 1699564800000,
"project": "api-server"
}
]
}
```
## How to Present Results
For format=index, present as a compact list:
```markdown
Found 5 user prompts about "authentication":
💬 **Prompt #1250** (Session #545)
> "How do I implement JWT authentication with refresh tokens? I need to handle token expiration..."
> Nov 9, 2024 • api-server
💬 **Prompt #1251** (Session #546)
> "The auth tokens are expiring too quickly. Can you help debug the refresh flow?"
> Nov 8, 2024 • api-server
```
For complete formatting guidelines, see [formatting.md](formatting.md).
## What Gets Searched
User prompts search covers:
- All user messages sent to Claude Code
- Raw text as typed by the user
- Multi-turn conversations (each message is a separate prompt)
- Questions, requests, commands, and clarifications
## Error Handling
**Missing query parameter:**
```json
{"error": "Missing required parameter: query"}
```
Fix: Add the query parameter
**No results found:**
```json
{"query": "foobar", "count": 0, "results": []}
```
Response: "No user prompts found for 'foobar'. Try different search terms."
## Tips
1. Use exact phrases in quotes: `?query="how do I"` for precise matches
2. Start with format=index to see preview, then get full text if needed
3. Use dateRange to find recent questions: `?query=bug&dateRange[start]=2024-11-01`
4. Prompts show what was asked, sessions/observations show what was done
5. Combine with session search to see both question and answer
**Token Efficiency:**
- Start with format=index (~50-100 tokens per result, prompt truncated to 200 chars)
- Use format=full only for relevant items (100-300 tokens per result)
- See [../principles/progressive-disclosure.md](../principles/progressive-disclosure.md)
## When to Use Prompts vs Sessions
**Use prompts search when:**
- Looking for specific user questions
- Trying to remember what was asked
- Finding original request wording
**Use sessions search when:**
- Looking for what was accomplished
- Understanding work summaries
- Getting high-level context
**Combine both when:**
- Understanding the full conversation (what was asked + what was done)
- Investigating how a request was interpreted

# Auto-detects project from current directory
curl -s "http://localhost:37777/api/context/recent?limit=3"
```
## Error Handling
**No sessions found:**
```json
{"project": "new-project", "sessions": []}
```
Response: "No recent sessions found for 'new-project'. This might be a new project."
**Worker not running:**
Connection refused error. Inform user to check if worker is running: `pm2 list`
## Tips
1. Start with limit=3 for quick overview (default)
2. Increase to limit=5-10 for deeper context
3. Recent context is perfect for session start
4. Combines both sessions and observations in one request
5. Use this when user asks "what did we do last time?"
**Token Efficiency:**
- limit=3 sessions: ~1,500-2,500 tokens (includes observations)
- limit=5 sessions: ~2,500-4,000 tokens
- limit=10 sessions: ~5,000-8,000 tokens
- See [../principles/progressive-disclosure.md](../principles/progressive-disclosure.md)
## When to Use Recent Context
**Use recent-context when:**
- Starting a new session
- User asks about recent work
- Need quick catch-up on project activity
- Want both sessions and observations together
**Don't use recent-context when:**
- Looking for specific topics (use search instead)
- Need timeline around specific event (use timeline instead)
- Want only observations or only sessions (use search operations)
## Comparison with Other Operations
| Operation | Use Case | Token Cost |
|-----------|----------|------------|
| recent-context | Quick catch-up on recent work | 1,500-4,000 |
| sessions search | Find sessions by topic | 50-100 per result (index) |
| observations search | Find specific implementations | 50-100 per result (index) |
| timeline | Context around specific point | 3,000-6,000 |
Recent context is optimized for "what happened recently?" questions with minimal token usage.

# Search Sessions (Full-Text)
Search session summaries using natural language queries.
## When to Use
- User asks: "What did we work on last week?"
- User asks: "What sessions involved database work?"
- User asks: "Show me sessions where we fixed bugs"
- Looking for past sessions by topic or theme
## Command
```bash
curl -s "http://localhost:37777/api/search/sessions?query=authentication&format=index&limit=5"
```
## Parameters
- **query** (required): Search terms (e.g., "authentication", "database migration", "bug fixes")
- **format**: "index" (summary) or "full" (complete details). Default: "full"
- **limit**: Number of results (default: 20, max: 100)
- **project**: Filter by project name (optional)
- **dateRange**: Filter by date range (optional)
## When to Use Each Format
**Use format=index for:**
- Quick overviews of past sessions
- Finding session IDs for deeper investigation
- Listing multiple sessions
- **Token cost: ~50-100 per result**
**Use format=full for:**
- Complete session summaries with requests, completions, learnings
- Understanding the full context of a session
- **Token cost: ~500-1000 per result**
## Example Response (format=index)
```json
{
"query": "authentication",
"count": 3,
"format": "index",
"results": [
{
"id": 545,
"session_id": "S545",
"title": "Implemented JWT authentication system",
"subtitle": "Added token-based auth with refresh tokens",
"created_at_epoch": 1699564800000,
"project": "api-server"
}
]
}
```
## How to Present Results
For format=index, present as a compact list:
```markdown
Found 3 sessions about "authentication":
🎯 **Session #545** Implemented JWT authentication system
> Added token-based auth with refresh tokens
> Nov 9, 2024 • api-server
🎯 **Session #546** Fixed authentication token expiration
> Resolved race condition in token refresh flow
> Nov 8, 2024 • api-server
```
For complete formatting guidelines, see [formatting.md](formatting.md).
## Session Summary Structure
Full session summaries include:
- **Session request**: What the user asked for
- **What was completed**: Summary of work done
- **Key learnings**: Important insights and discoveries
- **Files modified**: List of changed files
- **Observations**: Links to detailed observations
## Error Handling
**Missing query parameter:**
```json
{"error": "Missing required parameter: query"}
```
Fix: Add the query parameter
**No results found:**
```json
{"query": "foobar", "count": 0, "results": []}
```
Response: "No sessions found for 'foobar'. Try different search terms."
## Tips
1. Be specific: "JWT authentication implementation" > "auth"
2. Start with format=index and limit=5-10
3. Use dateRange for recent sessions: `?query=auth&dateRange[start]=2024-11-01`
4. Sessions provide high-level overview, observations provide details
5. Use project filtering when working on one codebase
**Token Efficiency:**
- Start with format=index (~50-100 tokens per result)
- Use format=full only for relevant items (~500-1000 tokens per result)
- See [../principles/progressive-disclosure.md](../principles/progressive-disclosure.md)
## When to Use Sessions vs Observations
**Use sessions search when:**
- Looking for high-level work summaries
- Understanding what was done in past sessions
- Getting overview of recent activity
**Use observations search when:**
- Looking for specific implementation details
- Finding bugs, features, or decisions
- Need fine-grained context about code changes

# Timeline by Query
Search for observations and get timeline context in a single request. Combines search + timeline into one operation.
## When to Use
- User asks: "What was happening when we worked on authentication?"
- User asks: "Show me context around bug fixes"
- User asks: "Timeline of database work"
- Need to find something then see temporal context
## Command
```bash
# Auto mode: Uses top search result as timeline anchor
curl -s "http://localhost:37777/api/timeline/by-query?query=authentication&mode=auto&depth_before=10&depth_after=10"
# Interactive mode: Shows top N search results for manual selection
curl -s "http://localhost:37777/api/timeline/by-query?query=authentication&mode=interactive&limit=5"
```
## Parameters
- **query** (required): Search terms (e.g., "authentication", "bug fix", "database")
- **mode**: Search mode
- `auto` (default): Automatically uses top search result as timeline anchor
- `interactive`: Returns top N search results for manual anchor selection
- **depth_before**: Records before anchor (default: 10, max: 50) - for auto mode
- **depth_after**: Records after anchor (default: 10, max: 50) - for auto mode
- **limit**: Number of search results (default: 5, max: 20) - for interactive mode
- **project**: Filter by project name (optional)
## Auto Mode (Recommended)
Automatically gets timeline around best match:
```bash
curl -s "http://localhost:37777/api/timeline/by-query?query=JWT+authentication&mode=auto&depth_before=10&depth_after=10"
```
**Response:**
```json
{
"query": "JWT authentication",
"mode": "auto",
"best_match": {
"id": 1234,
"type": "feature",
"title": "Implemented JWT authentication",
"score": 0.95
},
"timeline": [
// ... timeline records around observation #1234
]
}
```
**When to use auto mode:**
- You're confident the top result is what you want
- Want fastest path to timeline context
- Query is specific enough for accurate top result
## Interactive Mode
Shows top search results for manual review:
```bash
curl -s "http://localhost:37777/api/timeline/by-query?query=authentication&mode=interactive&limit=5"
```
**Response:**
```json
{
"query": "authentication",
"mode": "interactive",
"top_matches": [
{
"id": 1234,
"type": "feature",
"title": "Implemented JWT authentication",
"subtitle": "Added token-based auth with refresh tokens",
"score": 0.95
},
{
"id": 1240,
"type": "bugfix",
"title": "Fixed authentication token expiration",
"subtitle": "Resolved race condition in refresh flow",
"score": 0.87
}
],
"next_step": "Use /api/timeline/context?anchor=<id>&depth_before=10&depth_after=10"
}
```
**When to use interactive mode:**
- Query is broad and may have multiple relevant results
- Want to review options before getting timeline
- Not sure which result is most relevant
## How to Present Results
**For auto mode:**
```markdown
## Timeline: JWT authentication
**Best Match:** 🟣 Observation #1234 - Implemented JWT authentication (score: 0.95)
### Before (10 records)
**2:45 PM** - 🟣 Added authentication middleware
### ⭐ Anchor Point (2:55 PM)
🟣 **Observation #1234**: Implemented JWT authentication
### After (10 records)
**3:00 PM** - 🎯 Session completed: JWT authentication system
```
**For interactive mode:**
```markdown
Found 5 matches for "authentication":
1. 🟣 **#1234** Implemented JWT authentication (score: 0.95)
> Added token-based auth with refresh tokens
2. 🔴 **#1240** Fixed authentication token expiration (score: 0.87)
> Resolved race condition in refresh flow
To see timeline context, use observation ID with timeline operation.
```
For complete formatting guidelines, see [formatting.md](formatting.md).
## Error Handling
**Missing query parameter:**
```json
{"error": "Missing required parameter: query"}
```
Fix: Add the query parameter
**No results found:**
```json
{"query": "foobar", "top_matches": []}
```
Response: "No results found for 'foobar'. Try different search terms."
## Tips
1. **Use auto mode** for specific queries: "JWT authentication implementation"
2. **Use interactive mode** for broad queries: "authentication"
3. Start with depth 10/10 for balanced context
4. Be specific in queries for better auto mode accuracy
5. This is fastest way to find + explore context in one request
**Token Efficiency:**
- Auto mode: ~3,000-4,000 tokens (search + timeline)
- Interactive mode: ~500-1,000 tokens (search results only)
- See [../principles/progressive-disclosure.md](../principles/progressive-disclosure.md)
## Workflow Comparison
**timeline-by-query (auto):**
1. One request → get timeline around best match
2. ~3,000 tokens
**timeline-by-query (interactive) → timeline:**
1. First request → see top matches (~500 tokens)
2. Second request → get timeline for chosen match (~3,000 tokens)
3. Total: ~3,500 tokens
**observations search → timeline:**
1. Search observations (~500 tokens)
2. Get timeline for chosen result (~3,000 tokens)
3. Total: ~3,500 tokens
Use auto mode when you're confident about the query. Use interactive mode or separate search when you want more control.
## When to Use Timeline-by-Query
**Use timeline-by-query when:**
- Need to find something AND see temporal context
- Want one-request convenience (auto mode)
- Investigating "what was happening when we worked on X?"
- Don't have observation ID already
**Don't use timeline-by-query when:**
- Already have observation ID (use timeline instead)
- Just need search results (use observations search)
- Need recent work overview (use recent-context)

"created_at_epoch": 1699564900000
}
]
}
```
## How to Present Results
Present as chronological narrative with anchor highlighted:
```markdown
## Timeline around Observation #1234
### Before (10 records)
**2:45 PM** - 🟣 Observation #1230: Added authentication middleware
**2:50 PM** - 💬 User asked: "How do I add JWT authentication?"
### ⭐ Anchor Point (2:55 PM)
🟣 **Observation #1234**: Implemented JWT authentication
### After (10 records)
**3:00 PM** - 🎯 Session #545 completed: Implemented JWT authentication system
**3:05 PM** - 🔴 Observation #1235: Fixed token expiration edge case
```
For complete formatting guidelines, see [formatting.md](formatting.md).
## Anchor Types
**Observation ID:**
- Use when you know the specific observation ID
- Example: `anchor=1234`
**Session ID:**
- Use when you want context around a session
- Example: `anchor=S545`
**ISO Timestamp:**
- Use when you know approximate time
- Example: `anchor=2024-11-09T14:30:00Z`
## Error Handling
**Missing anchor parameter:**
```json
{"error": "Missing required parameter: anchor"}
```
Fix: Add the anchor parameter
**Anchor not found:**
```json
{"error": "Anchor not found: 9999"}
```
Response: "Observation #9999 not found. Check the ID or try a different anchor."
**Invalid timestamp:**
```json
{"error": "Invalid timestamp format"}
```
Fix: Use ISO 8601 format: `2024-11-09T14:30:00Z`
## Tips
1. Start with depth_before=10, depth_after=10 for balanced context
2. Increase depth for broader investigation (max: 50 each)
3. Use observation IDs from search results as anchors
4. Timelines show all record types interleaved chronologically
5. Perfect for understanding "what was happening when X occurred"
**Token Efficiency:**
- depth 10/10: ~3,000-4,000 tokens (21 records)
- depth 20/20: ~6,000-8,000 tokens (41 records)
- depth 50/50: ~15,000-20,000 tokens (101 records)
- See [../principles/progressive-disclosure.md](../principles/progressive-disclosure.md)
## When to Use Timeline
**Use timeline when:**
- Need context around specific event
- Understanding sequence of events
- Investigating "what was happening then?"
- Want all record types (observations, sessions, prompts) together
**Don't use timeline when:**
- Just need recent work (use recent-context)
- Looking for specific topics (use search)
- Don't have an anchor point (use timeline-by-query)
## Comparison with Timeline-by-Query
| Feature | timeline | timeline-by-query |
|---------|----------|-------------------|
| Requires anchor | Yes (ID or timestamp) | No (uses search query) |
| Best for | Known event investigation | Finding then exploring context |
| Steps | 1 (direct timeline) | 2 (search + timeline) |
| Use when | You have observation ID | You have search term |
Timeline is faster when you already know the anchor point.

# Anti-Pattern Catalogue
Common mistakes to avoid when using the HTTP search API. These anti-patterns address LLM training biases and prevent token-wasting behaviors.
## Anti-Pattern 1: Skipping Index Format
**The Mistake:**
```bash
# ❌ Bad: Jump straight to full format
curl -s "http://localhost:37777/api/search/observations?query=authentication&format=full&limit=20"
```
**Why It's Wrong:**
- 20 × 750 tokens = 15,000 tokens
- May hit MCP token limits
- 99% wasted on irrelevant results
**The Correction:**
```bash
# ✅ Good: Start with index, review, then request full selectively
curl -s "http://localhost:37777/api/search/observations?query=authentication&format=index&limit=5"
# Review results, identify relevant items
curl -s "http://localhost:37777/api/search/observations?query=authentication&format=full&limit=1&offset=2"
```
**What It Teaches:**
Progressive disclosure isn't optional - it's essential for scale.
**LLM Behavior Insight:**
LLMs trained on code examples may have seen `format=full` as "more complete" and default to it.
---
## Anti-Pattern 2: Over-Requesting Results
**The Mistake:**
```bash
# ❌ Bad: Request limit=20 without reviewing index first
curl -s "http://localhost:37777/api/search/observations?query=auth&format=index&limit=20"
```
**Why It's Wrong:**
- Most of 20 results will be irrelevant
- Wastes tokens and time
- Overwhelms review process
**The Correction:**
```bash
# ✅ Good: Start small, paginate if needed
curl -s "http://localhost:37777/api/search/observations?query=auth&format=index&limit=5"
# If needed, paginate:
curl -s "http://localhost:37777/api/search/observations?query=auth&format=index&limit=5&offset=5"
```
**What It Teaches:**
Start small (limit=3-5), review, paginate if needed.
**LLM Behavior Insight:**
LLMs may think "more results = more thorough" without considering relevance.
---
## Anti-Pattern 3: Ignoring Tool Specialization
**The Mistake:**
```bash
# ❌ Bad: Use generic search for everything
curl -s "http://localhost:37777/api/search/observations?query=bugfix&format=index&limit=10"
```
**Why It's Wrong:**
- Specialized tools (by-type, by-concept, by-file) are more efficient
- Generic search mixes all result types
- Misses filtering optimization
**The Correction:**
```bash
# ✅ Good: Use specialized endpoint when applicable
curl -s "http://localhost:37777/api/search/by-type?type=bugfix&format=index&limit=10"
```
**What It Teaches:**
The decision tree exists for a reason - follow it.
**LLM Behavior Insight:**
LLMs may gravitate toward "general purpose" tools to avoid decision-making.
---
## Anti-Pattern 4: Loading Full Context Prematurely
**The Mistake:**
```bash
# ❌ Bad: Request full format before understanding what's relevant
curl -s "http://localhost:37777/api/search/observations?query=database&format=full&limit=10"
```
**Why It's Wrong:**
- Can't filter relevance without seeing index first
- Wastes tokens on irrelevant full details
- 10 × 750 = 7,500 tokens for potentially zero useful results
**The Correction:**
```bash
# ✅ Good: Index first to identify relevance
curl -s "http://localhost:37777/api/search/observations?query=database&format=index&limit=10"
# Identify relevant: #1234 and #1250
curl -s "http://localhost:37777/api/search/observations?query=database+1234&format=full&limit=1"
curl -s "http://localhost:37777/api/search/observations?query=database+1250&format=full&limit=1"
```
**What It Teaches:**
Filtering is a prerequisite for expansion.
**LLM Behavior Insight:**
LLMs may try to "get everything at once" to avoid multiple tool calls.
---
## Anti-Pattern 5: Not Using Timeline Tools
**The Mistake:**
```bash
# ❌ Bad: Search for individual observations separately
curl -s "http://localhost:37777/api/search/observations?query=before+deployment"
curl -s "http://localhost:37777/api/search/observations?query=during+deployment"
curl -s "http://localhost:37777/api/search/observations?query=after+deployment"
```
**Why It's Wrong:**
- Misses context around events
- Inefficient (N searches vs 1 timeline)
- Temporal relationships lost
**The Correction:**
```bash
# ✅ Good: Use timeline tool for contextual investigation
curl -s "http://localhost:37777/api/timeline/by-query?query=deployment&depth_before=10&depth_after=10"
```
**What It Teaches:**
Tool composition - some tools are designed to work together.
**LLM Behavior Insight:**
LLMs may not naturally discover tool composition patterns.
---
## Why These Anti-Patterns Matter
**Addresses LLM Training Bias:**
LLMs default to "load everything" behavior from web scraping training data where thoroughness was rewarded.
**Teaches Protocol Awareness:**
HTTP APIs and MCP have real token limits that can break the system.
**Prevents User Frustration:**
Token limit errors confuse users and break workflows.
**Builds Good Habits:**
Anti-patterns teach the "why" behind best practices.
**Makes Implicit Explicit:**
Surfaces mental models that experienced users internalize but novices miss.
---
## What Happens If These Are Ignored
- **No progressive disclosure**: Every search loads limit=20 in full format → token exhaustion
- **Over-requesting**: 15,000 token searches for 2 relevant results
- **Wrong tool**: Generic search when specialized filters would be 10x faster
- **Premature expansion**: Load full details before knowing relevance
- **Missing composition**: Single-tool thinking, missing powerful multi-step workflows
**Bottom Line:** These anti-patterns waste 5-10x more tokens than necessary and frequently cause system failures.

# Progressive Disclosure Pattern (MANDATORY)
**Core Principle**: Find the smallest set of high-signal tokens first (index format), then drill down to full details only for relevant items.
## The 4-Step Workflow
### Step 1: Start with Index Format
**Action:**
- Use `format=index` (default in most operations)
- Set `limit=3-5` (not 20)
- Review titles and dates ONLY
**Token Cost:** ~50-100 tokens per result
**Why:** Minimal token investment for maximum signal. Get overview before committing to full details.
**Example:**
```bash
curl -s "http://localhost:37777/api/search/observations?query=authentication&format=index&limit=5"
```
**Response:**
```json
{
"query": "authentication",
"count": 5,
"format": "index",
"results": [
{
"id": 1234,
"type": "feature",
"title": "Implemented JWT authentication",
"subtitle": "Added token-based auth with refresh tokens",
"created_at_epoch": 1699564800000,
"project": "api-server"
}
]
}
```
### Step 2: Identify Relevant Items
**Cognitive Task:**
- Scan index results for relevance
- Note which items need full details
- Discard irrelevant items
**Why:** Human-in-the-loop filtering before expensive operations. Don't load full details for items you'll ignore.
### Step 3: Request Full Details (Selectively)
**Action:**
- Use `format=full` ONLY for specific items of interest
- Target by ID or use refined search query
**Token Cost:** ~500-1000 tokens per result
**Principle:** Load only what you need
**Example:**
```bash
# After reviewing index, get full details for observation #1234
curl -s "http://localhost:37777/api/search/observations?query=authentication&format=full&limit=1&offset=2"
```
**Why:** Targeted token expenditure with high ROI. 10x cost difference means selectivity matters.
### Step 4: Refine with Filters (If Needed)
**Techniques:**
- Use `type`, `dateRange`, `concepts`, `files` filters
- Narrow scope BEFORE requesting more results
- Use `offset` for pagination instead of large limits
**Why:** Reduce result set first, then expand selectively. Don't load 20 results when filters could narrow to 3.
## Token Budget Awareness
**Costs:**
- Index result: ~50-100 tokens
- Full result: ~500-1000 tokens
- 10x cost difference
**Starting Points:**
- Start with `limit=3-5` (not 20)
- Reduce limit if hitting token errors
**Savings Example:**
- Naive: 10 items × 750 tokens (avg full) = 7,500 tokens
- Progressive: (5 items × 75 tokens index) + (2 items × 750 tokens full) = 1,875 tokens
- **Savings: 5,625 tokens (75% reduction)**
## What Problems This Solves
1. **Token exhaustion**: Without this, LLMs load everything in full format (9,000+ tokens for 10 items)
2. **Poor signal-to-noise**: Loading full details for irrelevant items wastes tokens
3. **MCP limits**: Large payloads hit protocol limits (system failures)
4. **Inefficiency**: Loading 20 full results when only 2 are relevant
## How It Scales
**With 10 records:**
- Index (500 tokens) → Full (2,000 tokens for 2 relevant) = 2,500 tokens
- Without pattern: Full (10,000 tokens for all 10) = 4x more expensive
**With 1,000 records:**
- Index (500 tokens for top 5) → Full (1,000 tokens for 1 relevant) = 1,500 tokens
- Without pattern: Would hit MCP limits before seeing relevant data
## Context Engineering Alignment
This pattern implements core context engineering principles:
- **Just-in-time context**: Load data dynamically at runtime
- **Progressive disclosure**: Lightweight identifiers (index) → full details as needed
- **Token efficiency**: Minimal high-signal tokens first, expand selectively
- **Attention budget**: Treat context as finite resource with diminishing returns
Always start with the smallest set of high-signal tokens that maximize likelihood of desired outcome.

- Past work: "What did we do last session?"
- Bug fixes: "Did we fix this before?" or "What bugs did we fix?"
- Features: "How did we implement authentication?"
- Decisions: "Why did we choose this approach?"
- Code changes: "What files were modified in that refactor?"
- File history: "What changes to auth/login.ts?"
- Timeline context: "What was happening around that time?"
- Recent activity: "What have we been working on?"
**Do NOT invoke** for current session work or future planning (use regular tools for that).
## Quick Decision Guide
Once the skill is loaded, choose the appropriate operation:
**What are you looking for?**
- "What did we do last session?" → [operations/recent-context.md](operations/recent-context.md)
- "Did we fix this bug before?" → [operations/by-type.md](operations/by-type.md) (type=bugfix)
- "How did we implement X?" → [operations/observations.md](operations/observations.md)
- "What changes to file.ts?" → [operations/by-file.md](operations/by-file.md)
- "What was happening then?" → [operations/timeline.md](operations/timeline.md)
- "Why did we choose X?" → [operations/observations.md](operations/observations.md) (search for decisions)
## Available Operations
Choose the appropriate operation file for detailed instructions:
### Full-Text Search
1. **[Search Observations](operations/observations.md)** - Find observations by keyword (bugs, features, decisions, etc.)
2. **[Search Sessions](operations/sessions.md)** - Search session summaries to understand what was accomplished
3. **[Search Prompts](operations/prompts.md)** - Find what users have asked about in the past
### Filtered Search
4. **[Search by Type](operations/by-type.md)** - Find bugfix, feature, refactor, decision, or discovery observations
5. **[Search by Concept](operations/by-concept.md)** - Find observations tagged with specific concepts
6. **[Search by File](operations/by-file.md)** - Find all work related to a specific file path
### Context Retrieval
7. **[Get Recent Context](operations/recent-context.md)** - Get recent session summaries and observations for a project
8. **[Get Timeline](operations/timeline.md)** - Get chronological timeline around a specific point in time
9. **[Timeline by Query](operations/timeline-by-query.md)** - Search then get timeline around the best match
### Utilities
10. **[API Help](operations/help.md)** - Get API documentation
## Common Workflows
For step-by-step guides on typical user requests, see [operations/common-workflows.md](operations/common-workflows.md):
- Understanding past work
- Finding specific bug fixes
- Understanding file history
- Timeline investigation
## Response Formatting
For guidelines on how to present search results to users, see [operations/formatting.md](operations/formatting.md):
- Format=index responses (compact lists)
- Format=full responses (complete details)
- Timeline responses (chronologically grouped)
## Technical Notes
- **Port:** Default 37777 (configurable via `CLAUDE_MEM_WORKER_PORT`)
- **Response format:** Always JSON
- **Search type:** FTS5 full-text search + structured filters
- **All operations use HTTP GET** with query parameters
## Performance Tips
1. Use **format=index** first for overviews, then **format=full** for details
2. Start with **limit=5-10**, expand if needed
3. Use **project filtering** when working on one codebase
4. Use **timeline depth** of 5-10 for focused context
5. Be specific in search queries: "authentication JWT" > "auth"
## Error Handling
If HTTP request fails:
1. Inform user the search service isn't available
2. Suggest checking if worker is running: `pm2 list`
3. Offer to help troubleshoot
For detailed error handling, see the specific operation files.

```
---
## Format=Full Responses
When using `format=full`, present **complete details**.
### Observations (Full)
```markdown
### Observation #1234: Implemented JWT authentication
**Type:** Feature 🟣
**Project:** claude-mem
**Date:** Nov 9, 2024 3:30 PM
**Summary:** Added token-based auth with refresh tokens
**Details:**
Implemented a complete JWT authentication system for the API. The system uses
short-lived access tokens (15 minutes) combined with longer-lived refresh tokens
(7 days) to balance security and user experience. The implementation includes
middleware for route protection and automatic token refresh handling.
**Facts:**
- Used jsonwebtoken library (v9.0.2)
- Access tokens expire after 15 minutes
- Refresh tokens expire after 7 days
- Tokens include user ID and role claims
- Added rate limiting to auth endpoints
**Files Modified:**
- src/auth/jwt.ts (created, 145 lines)
- src/middleware/auth.ts (created, 78 lines)
- src/routes/auth.ts (created, 92 lines)
- tests/auth.test.ts (created, 234 lines)
**Concepts:** authentication, security, tokens, middleware
```
### Sessions (Full)
```markdown
### Session #123: Add user authentication (Nov 8, 2024)
**Request:** Implement JWT-based authentication for the API
**Completed:**
- Implemented JWT authentication system with access and refresh tokens
- Created authentication middleware for route protection
- Added login, logout, and token refresh endpoints
- Wrote comprehensive tests for auth flows
- Added rate limiting to prevent brute force attacks
**Learned:**
- JWT refresh token rotation is critical for security
- Need to handle token expiration gracefully on client side
- Rate limiting should be IP-based for auth endpoints
- Token blacklisting adds complexity, short expiration is simpler
**Next Steps:**
- Add password reset functionality
- Implement 2FA for admin accounts
- Add OAuth integration for social login
**Files Read:**
- docs/authentication-spec.md
- src/middleware/existing-auth.ts
- tests/integration/auth.test.ts
**Files Edited:**
- src/auth/jwt.ts (created)
- src/middleware/auth.ts (created)
- src/routes/auth.ts (created)
- tests/auth.test.ts (created)

> jsonwebtoken has better TypeScript support and simpler API
**5:15 PM** - 🟣 **Feature #1232:** "Created JWT utility functions"
> Sign, verify, and decode token helpers
### Nov 9, 2024
**3:30 PM** - 🟣 **Feature #1234:** "Implemented JWT authentication" ← ANCHOR
> Complete auth system with access and refresh tokens
**4:00 PM** - 🔴 **Bugfix #1235:** "Fixed token expiration edge case"
> Handled race condition in refresh flow
**4:30 PM** - ✅ **Change #1236:** "Updated API documentation"
> Added auth endpoint docs to README
```
**Legend:**
- 🎯 session-request
- 🔴 bugfix
- 🟣 feature
- 🔄 refactor
- ✅ change
- 🔵 discovery
- 🧠 decision
**Formatting Rules:**
1. Group by day with date headers
2. Show time for each item

## How to Present Results
```markdown
## Recent Work on claude-mem
### Session 1 (Nov 9, 2024 - Completed)
**Request:** Add user authentication
**Completed:**
- Implemented JWT authentication with token-based auth
- Added middleware for route protection
- Created login and refresh token endpoints
**Key Observations:**
1. 🟣 Implemented JWT authentication (#1234)
2. 🔴 Fixed token expiration edge case (#1235)
**Next Steps:**
- Add password reset functionality
- Implement rate limiting
---
### Session 2 (Nov 8, 2024 - Completed)
...
```
## Tips
1. This is the best operation for "what did we do recently" questions
2. Returns complete context including summaries and observations
3. Active sessions show current work in progress
4. Default limit=3 is usually sufficient for recent context

# Search Session Summaries
Search session-level summaries to understand what was accomplished in past sessions.
## When to Use
- User asks: "What did we accomplish in previous sessions?"
- Looking for sessions about a specific topic
- Understanding the scope of past work
## Command
```bash
curl -s "http://localhost:37777/api/search/sessions?query=deployment&format=index&limit=10"
```
## Parameters
- **query** (required): Search terms (e.g., "deployment", "bug fix", "refactor")
- **format**: "index" (summary) or "full" (complete details). Default: "full"
- **limit**: Number of results (default: 20, max: 100)
## Response Fields
- **request**: Original user request
- **completed**: What was accomplished
- **learned**: Technical learnings
- **next_steps**: Planned follow-ups
- **files_read**: Files that were read
- **files_edited**: Files that were modified
## Example Use Case
User asks: "Have we worked on deployment before?"
```bash
RESULT=$(curl -s "http://localhost:37777/api/search/sessions?query=deployment&format=index&limit=5")
# Parse JSON and present matching sessions
```
## How to Present Results
For format=index:
```markdown
Found 3 sessions about "deployment":
1. **Session #123** (Nov 8, 2024)
> Deploy Docker container to production
> Completed: Set up CI/CD pipeline, configured secrets
2. **Session #124** (Nov 9, 2024)
> Fix deployment rollback issues
> Completed: Added health checks, fixed rollback script
```
For format=full, include all fields (request, completed, learned, next_steps, files).
## Tips
1. Use format=index to find relevant sessions quickly
2. Then fetch format=full for complete details
3. Sessions capture high-level accomplishments vs observations (which are granular facts)

# Timeline by Query
Search for something, then automatically get timeline context around the best match.
## When to Use
- User asks: "What led to the authentication refactor?"
- Want to find something AND see surrounding context in one request
- Understand the full story with minimal requests
## Command
```bash
curl -s "http://localhost:37777/api/timeline/by-query?query=authentication+refactor&mode=auto&depth_before=10&depth_after=10"
```
## Parameters
- **query** (required): Search terms
- **mode**: Where to search (default: "auto")
- `"auto"`: Search both observations and sessions, return best match
- `"observations"`: Search only observations
- `"sessions"`: Search only sessions
- **depth_before**: Records before match (default: 10, max: 50)
- **depth_after**: Records after match (default: 10, max: 50)
- **project**: Filter by project name (optional)
## Response Structure
Returns both the best match AND timeline around it:
```json
{
"query": "authentication refactor",
"mode": "auto",
"match": {
"type": "observation",
"id": 1234,
"title": "Refactored authentication middleware",
"score": 0.95,
"created_at_epoch": 1699564800000
},
"depth_before": 10,
"depth_after": 10,
"timeline": {
"observations": [...],
"sessions": [...],
"prompts": [...]
}
}
```
## Use Case: "What led to the authentication refactor?"
One query gets both:
1. The authentication refactor observation (best match)
2. Complete timeline before and after showing what led to it
```bash
curl -s "http://localhost:37777/api/timeline/by-query?query=authentication+refactor&depth_before=10&depth_after=10"
```
## How to Present Results
```markdown
## Found: Refactored authentication middleware (Observation #1234)
**Match score:** 0.95
**Date:** Nov 9, 2024 3:30 PM
### Timeline (10 before → 10 after)
**Total:** 18 items (11 obs, 5 sessions, 2 prompts)
### Nov 8, 2024
**2:00 PM** - 🔴 **Bugfix #1220:** "Fixed token validation bug"
> Tokens weren't properly validated
**3:00 PM** - 🔵 **Discovery #1225:** "Current auth middleware is fragile"
> Multiple edge cases not handled
### Nov 9, 2024
**3:30 PM** - 🔄 **Refactor #1234:** "Refactored authentication middleware" ← MATCH
> Complete rewrite with better error handling
**4:00 PM** - ✅ **Change #1235:** "Updated all routes to use new middleware"
```
## Tips
1. This is the most efficient operation for "what led to X" questions
2. One request instead of two (search + timeline)
3. Use mode="auto" to search both observations and sessions
4. Adjust depth based on how much context you need
5. Great for understanding causality and sequence

# Get Timeline
Get a chronological timeline around a specific point in time.
## When to Use
- User asks: "What was happening when we fixed that bug?"
- Need context around a specific observation or session
- Understanding the sequence of events
## Command
```bash
# Around an observation ID
curl -s "http://localhost:37777/api/context/timeline?anchor=1234&depth_before=10&depth_after=10"
# Around a session ID
curl -s "http://localhost:37777/api/context/timeline?anchor=S123&depth_before=10&depth_after=10"
# Around a timestamp
curl -s "http://localhost:37777/api/context/timeline?anchor=2024-11-09T15:30:00Z&depth_before=10&depth_after=10"
```
## Parameters
- **anchor** (required): Observation ID (number), Session ID ("S123"), or ISO timestamp
- **depth_before**: Number of records before anchor (default: 10, max: 50)
- **depth_after**: Number of records after anchor (default: 10, max: 50)
- **project**: Filter by project name (optional)
## Response Structure
Returns unified timeline with observations, sessions, and prompts interleaved chronologically:
```json
{
"anchor": "1234",
"depth_before": 10,
"depth_after": 10,
"timeline": {
"observations": [...],
"sessions": [...],
"prompts": [...]
}
}
```
## Workflow: "What was happening when we fixed that auth bug?"
1. First, find the bug observation:
```bash
curl -s "http://localhost:37777/api/search/observations?query=auth+bug&format=index&limit=5"
# Get observation ID (e.g., #1234)
```
2. Then get timeline around it:
```bash
curl -s "http://localhost:37777/api/context/timeline?anchor=1234&depth_before=5&depth_after=5"
```
## How to Present Results
Present chronologically grouped by day:
```markdown
## Timeline around Observation #1234
**Window:** 5 records before → 5 records after
**Total:** 12 items (7 obs, 3 sessions, 2 prompts)
### Nov 8, 2024
**4:30 PM** - 🎯 **Session Request:** "Add user authentication"
**4:45 PM** - 🔵 **Discovery #1230:** "JWT library options compared"
> Evaluated 3 libraries: jsonwebtoken, jose, passport-jwt
**5:00 PM** - 🧠 **Decision #1231:** "Chose jsonwebtoken for simplicity"
### Nov 9, 2024
**3:30 PM** - 🟣 **Feature #1234:** "Implemented JWT authentication" ← ANCHOR
**4:00 PM** - 🔴 **Bugfix #1235:** "Fixed token expiration edge case"
> Handled race condition in refresh flow
```
**Legend:** 🎯 session-request | 🔴 bugfix | 🟣 feature | 🔄 refactor | 🔵 discovery | 🧠 decision
For complete formatting guidelines, see [formatting.md](formatting.md).
## Tips
1. Use depth_before=5, depth_after=5 for focused context
2. Increase depth for broader investigation
3. Timeline shows the full story around a specific point
4. Helps understand causality and sequence of events

/**
* New Hook - UserPromptSubmit
* Consolidated entry point + logic
*
* DUAL PURPOSE HOOK: Handles BOTH session initialization AND continuation
* ==========================================================================
*
* CRITICAL ARCHITECTURE FACTS (NEVER FORGET):
*
* 1. SESSION ID THREADING - The Single Source of Truth
* - Claude Code assigns ONE session_id per conversation
* - ALL hooks in that conversation receive the SAME session_id
* - We ALWAYS use this session_id - NEVER generate our own
* - This is how NEW hook, SAVE hook, and SUMMARY hook stay connected
*
* 2. NO EXISTENCE CHECKS NEEDED
* - createSDKSession is idempotent (INSERT OR IGNORE)
* - Prompt #1: Creates new database row, returns new ID
* - Prompt #2+: Row exists, returns existing ID
* - We NEVER need to check "does session exist?" - just use the session_id
*
* 3. CONTINUATION LOGIC LOCATION
* - This hook does NOT contain continuation prompt logic
* - That lives in SDKAgent.ts (lines 125-127)
* - SDKAgent checks promptNumber to choose init vs continuation prompt
* - BOTH prompts receive the SAME session_id from this hook
*
* 4. UNIFIED WITH SAVE HOOK
* - SAVE hook uses: db.createSDKSession(session_id, '', '')
* - NEW hook uses: db.createSDKSession(session_id, project, prompt)
* - Both use session_id from hook context - this keeps everything connected
*
* This is KISS in action: Use the session_id we're given, trust idempotent
* database operations, and let SDKAgent handle init vs continuation logic.

* - Same session_id used by SAVE hook to store observations
* - This is how everything stays connected in one unified session
*
* NO SESSION EXISTENCE CHECKS NEEDED:
* - SessionManager.initializeSession already fetched this from database
* - Database row was created by new-hook's createSDKSession call
* - We just use the session_id we're given - simple and reliable
